The format of the Export List File record is designed to allow for ease of use. It is
expected that you may input the needed information manually and the format
needs to be tolerant of the location of the fields in the record. Each list file record
contains up to two fields that are separated by a delimiter. The fields "volser" and
"destination" must be displayed in that order, separated by a field delimiter. If the
record is not equal to 80 bytes, the record is not processed and a Status File record
is written with a status code of 24. The first 13 bytes or less of data from the record
as read is provided in the Status File record. If only one field is found in the
record, it is assumed that a blank destination is desired.

Description
Volser
The volume serial number of a logical volume to be exported. The VTS
uses six characters to identify the volser, starting with the first
non-blank character and continuing until six non-blank characters have
been found. Valid characters are A–Z and numerics 0–9. The search for
six non-blank characters continues until a blank or delimiter comma
character is found.
Note: If the volser found is not six characters or contains non-valid
characters, a Status File record is written with a status code of 1E and
with the first 13 bytes of the list record.
Field Delimiter
Comma character required if a non-blank destination is specified.
Destination
The destination for the logical volume. The control unit uses up to
16 characters, starting with the first non-blank character after the field
delimiter and continuing through byte 71, for the destination name.
Embedded blanks are allowed in the destination name. Any characters
in the record after the destination field are ignored. No validity
checking is performed on the name found. A blank destination is also
valid; however, all characters after the volser or delimiter comma and
throughout byte 71 must be blank.
User Field
Bytes 72–79 of the 80-byte record are not used or checked by the VTS.
This field may contain line numbers for volume lists.

recl>=1. This record must be present; however, neither its length nor

Note: The minimum record length written to tape is 18 bytes.
N is a variable number of file records. N=0 is valid, recl>=1, records
not checked or used by the control unit.
Note: The minimum record length written to tape is 18 bytes.
